Timing system and method of data transmission system

The invention provides a timing system and method of a data transmission system. The system divides different application levels of levels of clocks to meet the demands of different data transmissionsystems on the lowest accuracy and the traction range. In the timing system and method provided by the invention, the traditional design method is broken through, the timing of the system is directlyaccomplished via the timing system device functions by using the system integration technology in three manners of wireless communication, fiber communication and wired communication, the three manners are integrated in a data transmission device, the purpose of accurate synchronization of three timing times in the device is achieved, and the timing system has the advantages of small size, high integration, installation and convenient use, system stability, good compatibility. 本发明提供了种数传系统时统系统及方法，系统对各级时钟划分出不同的应用等级，以应对不同的数传系统对最低准确度和牵引范围的需求。在本发明中，突破了传统的设计方法，利用系统集成技术直接将时统设备功能通过无线通信、光纤通信和有线通信三种方式完成系统时统，三种方式互为备份集成到数传设备中，达到了在
